“The Ghosts of Christmas Eve” are Trans-Siberian Orchestra’s own this year, having lost founder Paul O’Neill to a prescription drug overdose and bassist David Z in an RV accident in Florida.

But the show goes on, and the group that has sold 10 million records will bring its high-tech laser lights and pyro effects, zooming guitar licks and holiday themes to Mohegan Sun Arena for two “Ghosts of Christmas Eve” shows Sunday, Nov. 26.

In a release, TSO said the tour will be a celebration of the art and accomplishments of the group’s late creator/composer/lyricist O’Neill (who had health issues that included a chronic spine problem) and his “inimitable creation,” which he called “Rock Theater.”

In 1996, O’Neill launched Trans-Siberian Orchestra with a vision for a band that was theatrical, conceptual and ever-changing, says a TSO release. The new music director is lead guitarist Al Pitrelli, a member in 1999 and 2001 to the present.

The new winter tour (which began mid-month) presents an updated version of TSO’s classic “The Ghosts of Christmas Eve” and will visit more than 60 cities, for 100-plus performances, before concluding on Dec. 30th.
